I agree about the energy use of PoW. On Ethereum, the PoS beacon chain has been live for almost a year now [1], with the merging of the PoW and PoS networks happening next year. We're now at the point where the specs for the merge transition are ready [2], clients are already being modified to target the release-spec [3], and the first long-lived testnet will go live by December. I'd personally expect the Merge to happen by May.
